Chapter 5 - Sutra 12-16
The support field is considered to be double by nature. Thus, the support field of a soul or living being can increase in a sequence of threefold, fourfold, fivefold, and so on, eventually becoming innumerable, that is, a spatial infinity. The support field of one life can only become a spatial infinity when that soul is in a state of liberation. Due to the minimalism of the soul's dimension, the limitation on its support field's dimension must be understood in the expectation of a plant; in terms of living beings, the support field of the living essence is a complete spatial infinity.
Now the question arises as to why there is seen a variation in dimension with respect to time for two souls of equal regions in the material dimension, or why there is seen a variation in dimension for different souls at the same time. The answer provided here is that the variations in the dimensions of one soul or different souls occur in relation to those particles which have been with the soul since beginningless time and which possess infinite atomic aggregation. Karmas do not always remain the same; the other bodies obtained in relation to them also vary according to karma, having slight differences. There are six substances; in reality, they exist. However, due to the connections, they become mutable. Therefore, whenever one receives a body of substance, its dimension will only be as much as that body is.
